Answer is DICE
Its Always 1 to 6: numbers on all sides
Its Always 15 to 20: total of all numbers on dice viewable on rest is always between 15 to 20 ( 1+2+3+4+5=15 or 2+3+4+5+6=20)
Its always 5: When on rest one can see only 5 sides
Its never 21 unless its flying: if on rest its total can be 15 to 20 but when flying in air total of numbers of all side is 21(1+2+3+4+5+6)
